Torus Ti CXob Frame

This is the Ti Cyclo-cross race bike.  We call it the One Bike, or TiCX-ob.  It's designed to finish every CX race without having to change bikes.  It's designed to work in mud.  Drawing on our experience from MTB racing we have designed the drivetrain to cope with the most arduous muddy race conditions. We've tested it over 2 CX seasons and we are confident it works

The frame is 1x specific - no front mech.  

It uses an 142mm rear hub with an mtb style 1x specific clutch type mech that does actually work in mud - so no more mud induced chain suck resulting in snapped mech hangers or derailleurs.

The mud clearance is as big as is possible - so no more mud clogging around the fork or the bottom bracket/chainstay area.  

It's disc specific.

It's externally routed - there are no holes to fill up with water!

It's titanium so it's smooth

It's ace!
